This Bottom Outlet Stainless Steel Dual Booster Valve manufactured by Joepai is a core inlet assembly for Australian commercial, industrial and residential fire hydrant systems, designed to boost water pressure from fire trucks during emergencies.
All key internal parts adopt grade 304 stainless steel, effectively solving rust and leakage problems of ordinary cast iron boosters, supporting over 10 years stable service life for underground parking lots, seaside projects and high-rise buildings.
The valve arrives pre-assembled with all supporting hardware, paired with a clear installation manual to cut construction time and reduce extra accessory purchasing costs.

Nominal pressure: PN14
Working pressure: 1400kPa
Hydraulic test pressure: 2100kPa
Main connection: DN100 roll groove
Fire brigade port: DN65 Storz hose connector
Optional inlet: Queensland round thread
2 mounting versions: compact back mount, vertical bottom mount
Check all supplied parts: pre-assembled valve body, 2 ball valves, pressure gauge and dust cap sets
Mount the booster valve to pipeline booster points via DN100 roll groove coupling (not provided)
Wrap around 3 layers of thread seal tape on the pressure gauge thread for reliable sealing
Screw the pressure gauge into the top middle isolation ball valve, tighten with spanner and adjust the gauge facing forward for easy reading
Keep drain valve fully open during initial water filling to exhaust internal air; close the drain knob only after all air is fully bled
Open the gauge isolation valve and confirm the pressure gauge displays pipeline data normally
Carry out 1-minute full pressure leakage inspection on all joints and connections
Cover both Storz ports with dust caps linked by chains to finish installation
Thread seal tape wrapping is required to prevent thread joint water leakage
Fully bleed air before closing drain valve to avoid air lock and inaccurate pressure readings
1-minute pressure leakage test is required to meet Australian fire engineering acceptance standards
Cast iron boosters easily rust and leak within several years. Our stainless steel structure resists salt fog and long-term outdoor dampness, greatly lowering later maintenance costs.
All ball valves, pressure gauge and drain fittings are pre-installed at factory. The operation guide helps fire installers finish assembly faster without sourcing separate spare parts.
Follows AS 2419.3-2012 standard, can pass official fire brigade inspection without secondary modification for contractors and real estate developers.
Compact back and vertical bottom installation options fit different building pipe layouts, suitable for malls, warehouses, apartments and public facilities.
One-piece dual booster housing reduces leakage risks from split pipe joints and saves installation space compared with two separate single boosters.
Our Bottom Outlet Stainless Steel Dual Booster Valve is a go-to solution for fire protection projects all across Australia. It works perfectly for high-rise office towers, retail shopping centres, hotels and multi-unit residential apartment buildings. You’ll also find it installed in manufacturing factories, large logistics storage warehouses and chemical processing facilities. Other common sites include underground car parks, medical hospitals, local schools and public sports stadiums. If you’re working on coastal building developments, harbours or marine fire safety setups, this booster valve is built to handle those harsh salt-air conditions too. Fire system tradespeople and businesses offering regular fire hydrant servicing & compliance checks also rely heavily on this model.
A: Absolutely. Every full kit includes a physical printed guide that walks you through the whole process – fitting the valve to pipework, attaching the pressure gauge, purging air from the lines and carrying out leak testing.
A: It’s designed exactly for that environment. All key internal parts are made from grade 304 stainless steel, plus the exterior has a fusion bonded anti-corrosion coating, so it resists salt spray damage extremely well for seaside builds.
A: The roll groove couplings needed to mount the valve onto your main pipeline are not included in the set; you will need to source these separately on site.
A: We offer two main fitting styles: compact rear mounting and vertical bottom mounting, which adapt to a wide range of existing building pipe setups.
A: Its standard working pressure rating sits at 1400kPa, and every unit undergoes factory testing up to 2100kPa, delivering steady reliable performance within high-pressure fire water mains.
